BRAlDlNG ATTACHMENT FO R EMBROlDERlNG-MACHINES.

.J'JECIFECATION forming part of Letters Patent No. 303,724, dated August 19, 1884.

Application filed July 18, B83. (No model.)

To (ZZZ who/I1, it Iltbj/ concern:

Beit known that I, J noon GRAF, of the city, county, and State of New York, have invented certain new and useful Improvements in Braiding Attachments to EmbroideringMachines, of which the following is a specification.

This invention has reference to an improved braiding attachment that is specially adapted for use on the embroidering-machines patented by Antoine Bonnaz, Nos. 83,909 and 83,910, dated November 10, 186.8, and to Emile Cornely, No. 182,804, dated October3, 1876; and the invention consists of a spool-holder at the upper part of the needle-bar from which the braid is conducted through the hollow presscrbar along a side recess of the needle-bar to a nipple at the lower end of the presscr-bar and through a guard at the lower end of the nipple across the needle; and the invention consists, secondly, of the specific construction of the needle-bar, hollow presser-bar, and nipple, as will be more fully described hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of a Bonnaz embroidering-machine with my improved braiding attachment. Fig. 2 is a sample of embroidery accomplished by my attachment. Fig. 3 is a vertical central sectionof the needle-bar and presser-bar of my improved braiding attachment drawn on alarger scale. Figs.

4 and 5 are details of the holder for the braid spool. Fig. 6 is a horizontal section on line w 00, Fig. 3. Fig. 7 is a detail view of the nipple at the lower end of the presscr-bar, and Figs. 8 and 9 are respectively ahorizontal section and a bottom view of the nipple.

Similar letters of reference indicate corresponding parts.

My improved braiding attachment is used in connection with the well-known Bonnaz embroideringmaehines, for the general construction of which reference is made to the patents heretofore mentioned. To the upper part of the presser-bar A of said machine is applied a cross-piece, a, having uprights aa, carrying a yoke, I). The yoke b carries the spindle d for the spool B,upon which the braid is wound.

Either flat or round braid may be used with my improved attachment. The spool turns freely on the spindle d in paying out the braid,

and is detachable with the same from the yoke. From the spool the braid is conducted through an inclined downward]yextending opening, 0, in the upper part of the presser-bar, and along a longitudinal side recess, 0, of the needle-bar O to thelower section, A, of the hollow presscrbar A, and through an inclined opening, a, of said lower sect-ion to the outside and downward along a guide-socket, D, that isserewed into the lower end of the section A of the presser-bar A to a nipple, D, whiehis guided on the lower part of the socket D. The nipple D is provided with a central perforation for the needle, and a collar, f, and asidewiseprojecting guard, f, at the lower end. The braid is passed through said guard f and conducted below the central needle-hole of said nipple, and agroove or recess, f at a point diametrically opposite to said guard f of the nipple, as shown clearly in Fig. Between the collar f of the nipple D and a flange, f, at the upper end of the guide-socket D, which flange abuts against the lower end of the presser-bar A, is interposed a spiral spring, which serves as a cushioning-spring for the nipple D and regulates the even forward feeding of the braid as required by the work. The lower section, A, of the presser-bar A is guided by its sleeve-shaped upper end in the upper part of the presscr-bar, which latter is tightly clamped by a setscrew, h, to the needle-bar. The lower section, A, recedes as the needle-bar descends and moves downward by gravity when the needle-bar is raised. The

needle passes througl'l the center of the braid and applies the same evenly and regularly to the fabric. The braid is guided along the needle-bar, presser-bar, and nipple, and paid out by the latter in connection with the feeding mechanism by which the fabric is fed forward on the machine.

A very simple and effective braiding attachment for embroidering-machines of the class mentioned is thus supplied, by which round or fiat braids of different sizes may be stitched in a quick and uniform manner to the fabrics to. be embroidered.

Having thus described my invention, I claim as new and desire to secure by Letterslatent- 1. In an embroidering-machine of the type described,the combination of a longitudinallyrecessed needle-bar, a hollow presser-bar, the upper section of which is clamped to the needie-bar and carries a spool holder for the braid, a lower sliding section having a fixed guide-socket at the lower end, and a springcushioned nipple guided on said socket, said nipple being provided with a braid-guard at one side, substantially as set forth.

2. In an embroidei'ing-machine of the ype described,the combination of a longitudinallyrecessed needle-bar, 0, a hollow presser-bar, A, the upper section of which is clamped to the needle-bar, and a lower movable section, A, the sections being provided, respectively, with guide-openings for the braid, a guidesocket, D, attached to the lower end of the movable section A, and a spring -cushioned nipple, D, guided on the lower part of the socket D, said nipple being provided with a braid-guard at one side and a guide-recess at the opposite side, substantially as set forth.

r). The combination, in a braiding attachment for einbroidering-machines, of a guidesocket, a braid-guiding nipple provided with a collar and with a braidguard at the lower end thereof, and a spring interposed between said collar of the nipple and the head of said guide-socket, substantially as set forth.

L'ThG combination, in a braiding attachment for embroidering-lnachines, of a guidc socket, a braid-guiding nipple provided with a c01lar,and having at its lower end a braidguard at one side and a guide-recess at the opposite side, and a spring interposed between said collar of the nipple and the head of said guidesocket, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
